Naoki's big brother revealed that he is an infinite regressor. He broke the cycle and came to Earth to guide him to the world where he is destined to rule. He also revealed a prophecy, that Naoki is the destined one.After that, Naoki reincarnated as Aether von Noctvain, heir to one of the Seven Great Families of the Empire.However, as he begins to uncover hidden truths, he discovers that the prophecy was a lie, crafted by Celestial beings who feared his brother's power.Enraged, he vowed to avenge his brother. Even as a mere mortal, he killed a demi-god. As punishment for killing a celestial being, his mana was sealed.Soon after, his own companions betrayed him. The entire world turned against him, branding him a heretic who rebelled against divinity.They even killed his family and his fiancée.Through an ancient relic, Aether is sent back in time. This time, he will make everyone pay, He will strip their skin away with cruelty, fueled by madness.“I swear, I will raise those I cherish to heights no god can reach and drag every traitor screaming into hell,Even if it drives me past the edge of madness.”Let vengeance walk beside insanity.Let sanity shatter.The gods spoke of salvation, but offered only chains. butThey miscalculated one thing:Aether von Noctvain does not beg fate.He is the hand that will make fate bleed.

Though he received the skills necessary to teleport across worlds, the king who performed the summoning ritual attempted to trick him into wearing a slavery collar, this annoyed him so he kidnapped the princess and returned to Earth.

In a single moment, he had lost everything he possessed.His father had disowned him; he had lost his title as prince, and the nobles he had considered his friends had turned their backs on him. Finally, he had been exiled.And it was all because of the “Otherworldly Shopping System.”Still, no one, including Luke, could understand the value of this ability. As hope faded from his heart, it reappeared in the farthest northern region of the Empire, in a freezing cold area.10,000 cubic metres of water to irrigate the land? You can get it for just three gold coins.Perhaps he should establish a new farm? 100 high-quality cows for just 200 gold.Perhaps he wishes to establish a clothing workshop? Building a ready-made structure would only cost 500 gold.This is his opportunity, the opportunity of Luke, the Light of the Empire. An abandonment worth a world.
